The invention relates to a method for computer-implemented monitoring of a wind turbine having a rotor with rotor blades (10). The rotor blades (10) are provided with an active flow control device (11D, 12D, 14D). During the operation of the wind turbine the following steps are performed: i) obtaining digital operation data (OD) of the wind turbine, the operation data (OD) being current sensor data (WTSD) taken by a plurality of sensors installed on the wind turbine and a control signal (AFCD CS) for controlling the active flow control device (11D, 12D, 14D) to adopt a specific state; ii) determining an estimate (ECLI) of the state and / or performance degradation of the active flow control device (11D, 12D, 14D) by processing the operation data (OD) by a trained data driven model (DDM), where the operation data (OD) are fed as a digital input to the trained data driven model (DDM) and the trained data driven model (DDM) provides the estimate (ECLI) of the state and / or performance degradation of the active flow control device (11D, 12D, 14D) as a digital output.

Disclosed are an oil drain valve (100), an energy accumulation device (200), a hydraulic system and a working machine. The oil drain valve includes a valve body (1), a valve core (2) and an elastic element (3). The valve body is provided with a first oil port (11) and a second oil port (12), the valve core is communicated with the first oil port and the second oil port, and the valve core is movable in the valve body to switch from a first working position to a second working position. The elastic element is provided between a first end of the valve core and the valve body, the first end of the valve core is communicated with the first oil port, and a second end of the valve core is communicated with the second oil port. In response to that hydraulic oil in the oil drain valve flows from the first oil port to the second oil port, the valve core is configured to move from the second working position to the first working position under an action of the elastic element; and in response to that the hydraulic oil in the oil drain valve flows from the second oil port to the first oil port, the valve core is configured to compress the elastic element and switch from the first working position to the second working position. A flow quantity of the oil drain valve in response to that the valve core operates in the second working position is less than a flow quantity of the oil drain valve in response to that the valve core operates in the first working position.

Systems and methods for automatically controlling landing gear responsive to detected aerial vehicle conditions. A system can receive, from one or more sensors of the aerial vehicle, altitude information and speed information of the aerial vehicle. The system can determine to lower landing gear of the aerial vehicle based on a change in a state of the aerial vehicle, and identify a condition corresponding to a type of the aerial vehicle and the state of the aerial vehicle. The system can compare the speed information and the altitude information to the condition to determine that a condition to lower landing gear is satisfied. Responsive to determining that the condition to lower the landing gear is satisfied, the system can provide a signal to lower the landing gear.
